Do you hate when people attempt to borrow your car? Do you think a joy buzzer handshake is a clever prank? If you answered yes to both of those questions then we have a device for you: the Shocks Car Key. Designed by Bim Bam Banana, the fake key fob gives the user a mild electric shock when they try and open the car. While we wouldn't use it on our friends, because we like them and we don't usually spend $21 on novelties, we wouldn't hesitate to use it on younger siblings that insist on taking the car without permission.
